This proprietary MotoSport guide walks you through safely flushing and replacing the brake fluid on a 2016 Polaris Scrambler XP 1000, with model-specific notes that owners should know before starting.

What you need

  • DOT 4 brake fluid (fresh, unopened)
  • Clear plastic tubing to fit the bleed nipple
  • Catch bottle or jar (marked for brake fluid)
  • Wrench for bleed nipples (typically 8mm or 10mm)
  • Turkey baster or fluid syringe (optional for reservoir removal)
  • Brake-cleaner, rags, nitrile gloves & eye protection
  • Floor jack, stands or ramps to elevate the ATV safely
  • Optional: vacuum or pressure brake bleeder for one-person bleeding

Important 2016 Polaris Scrambler XP 1000 notes

  • The Scrambler XP 1000 uses separate front and rear brake systems with two handlebar reservoirs typically for front and a frame-mounted reservoir for rear or a combined configuration depending on trim. Verify reservoir locations before starting.
  • There is no factory ABS system on most 2016 Scrambler XP 1000 models – this simplifies bleeding but do not assume hardware differs; inspect your machine for any aftermarket parts.
  • Brake calipers are exposed to off-road contaminants. Clean around the master cylinder cap and bleed nipples before opening to prevent contamination.
  • Brake fluid will damage painted and plastic surfaces. Wipe spills immediately and flush affected areas with water if needed.

Safety first

  • Work on a flat, stable surface and secure the ATV so wheels can turn freely if needed.
  • Wear gloves & eye protection. Dispose of old fluid per local regulations.
  • Never let the master cylinder reservoir run dry during bleeding — introduction of air will require restarting the process.

Step-by-step: flush & replace brake fluid

1. Prep the machine

  • Park, kill the engine, and remove the key. Clean the area around the master cylinder caps thoroughly.
  • Raise the ATV so the wheels can be worked safely if necessary. Remove wheels only if it makes accessing bleed nipples easier.
  • Open the master cylinder reservoir(s) and remove as much old fluid as possible with a syringe or turkey baster. Do not mix old & new fluid in the reservoir.
  • Refill the reservoir with fresh DOT 4 brake fluid to the fill line. Keep the cap loosely on to minimize contamination.

2. Identify bleeding order

  • Always bleed the caliper farthest from the master cylinder first, then work toward the closest. For the Scrambler layout that often means: rear caliper first (if rear has a separate reservoir), then the front calipers from the farthest front wheel to the nearest. If your bike has a single combined reservoir, still use farthest-to-closest rule.

3. Two-person manual bleed (recommended for most DIYers)

  • Attach clear tubing to the bleed nipple and submerge the other end in a catch bottle partially filled with old fluid to prevent air re-entry.
  • One person pumps the brake lever or pedal slowly several times and holds pressure. The other person opens the bleed nipple about a quarter-turn to let fluid & air escape, then closes it before pressure is released. Repeat until the fluid runs clear and free of bubbles.
  • Top up the reservoir frequently to keep it from going below the minimum line.
  • Work through each caliper in the correct order until all circuits run clear.

4. One-person vacuum or pressure bleed

  • Attach a hand vacuum pump to the bleed nipple or use a pressure bleeder on the master cylinder reservoir per manufacturer instructions.
  • If using vacuum, pump while the bleed nipple is open until fluid is clear and bubble-free; close nipple before releasing vacuum.
  • If using pressure bleeder, pressurize the reservoir per tool instructions and open bleed nipples sequentially until clear.

5. Final steps

  • When no air bubbles appear and fluid is clear, close the last bleed nipple tightly while the brake lever/pedal is held down (if using manual method) to avoid sucking air back in.
  • Top off the reservoir to the proper level, reinstall caps & seals, and clean any spilled fluid. Reinstall wheels if removed and torque fasteners to factory spec.
  • Carefully test the brake feel at low speed in a safe area. If the lever or pedal feels spongy, repeat the bleed until firm.
  • Properly dispose of used brake fluid. Keep a maintenance log of the date and mileage when the fluid was changed.

Troubleshooting

  • Persistent sponginess: likely air still in the system & repeat bleeding needed. Inspect for leaking master cylinder seals, cracked hoses or loose connections.
  • Brake fade after fluid change: ensure correct DOT 4 fluid used and that reservoirs were filled to the correct level. If contamination suspected, repeat flush.
  • If you suspect internal master cylinder problems (soft lever even after bleeding), consider rebuild or replacement.

Maintenance interval advice

Change brake fluid every 1-2 years or sooner for heavy off-road use. Fresh fluid maintains boiling point and prevents moisture-related corrosion inside the system.

Model-care tips for the Scrambler XP 1000

  • Regularly inspect caliper pistons for dirt ingress after muddy rides and clean before bleeding to avoid dragging or contamination.
  • Keep master cylinder reservoir caps and diaphragms in good condition to prevent moisture entry during storage.
  • Check brake hose routing for chafing or abrasion points common on aggressive terrain setups; replace any damaged hoses immediately.
